Einstein

Juan Maldacena , Carl P. Feinberg Professor in the School of Natural Sciences, and Member Douglas Stanford will give the public lecture “ The Cool Alter-Ego of a Black Hole ,” on Friday, May 4 , which will take...
It is as if the scientific disciplines are formed in strata, like the geological layers on display in the Grand Canyon. Moving from one layer to another, we see examples of emergence and reductionism, these two overarching organizing principles of modern science. Zooming out, we see new patterns “emerge” from the complex behavior of individual building blocks. Biochemical reactions give rise to sentient beings. Individual organisms gather into ecosystems. Hundreds of billions of stars come together to make majestic swirls of galaxies. As we reverse and take a microscopic view, we see reductionism at work.
Albert Einstein, one of the Institute's first Faculty members, argued that what we understand as gravity is, in fact, from the curvature of space and time — a hotly debated notion among physicists at the time. Then came the solar eclipse of 1919 — more...
Scientists look around the universe and see amazing structure. There are objects and processes of fantastic complexity. Every action in our universe follows exact laws of nature that are perfectly expressed in a mathematical language. These laws of nature appear fine-tuned to bring about life,...
The conflict between the two halves of physics has been brewing for more than a century—sparked by a pair of 1905 papers by Einstein , one outlining relativity and the other introducing the quantum—but recently it has entered an intriguing, unpredictable new phase. Two...
For the third time in less than two years, physicists have detected billion-year-old ripples in the fabric of space-time. The new recording, like the two others before it, was made using the Laser Interferometer Gravitational-Wave Observatory ( LIGO ). . . . LIGO's third...
Einstein was a true genius and it’s the example that we all aspire to be as a scientist. But already as a child he had a very original way of thinking. So from the very beginning, for Einstein, his imagination was crucial. View the...
What struck me was some regularity in the anomaly. The rotational velocities were not just larger than expected, they became constant with radius. Why? Sure, if there was dark matter, the speed of stars would be greater, but the rotation curves, meaning the rotational speed...
Perhaps the most fundamental philosophical question that you can ask in science is: "Why are we here?" To understand the universe, we have to bring together the two key ideas that are governing modern physics. On the one hand, we have Einstein’s theory of...
Though it may seem far removed from the noise of the contemporary world, the Institute for Advanced Study (IAS) has a long history of combating threats to its scholars and their work. Recent executive orders by President Trump attempting to enforce travel bans and immigration...
Einstein’s general theory of relativity taught us that the universe is expanding, but we have only recently discovered the pace of that expansion and its consequences. View the video at Business Insider as Robbert Dijkgraaf , Institute Director and Leon...
Gravitational waves were detected for the first time a year and a half ago, when some of them throbbed through Earth. Two incredibly sensitive detectors—one in Washington State and one in Louisiana—picked up the distortions in spacetime, emanating in this case from two merging black...
